My invention relates to improvements in welding shields and the objectof my invention is to devise a shield Which will effectively andcompletely protect 'the eyes of the operator from the light raysof thewelding flame. V

It has been found that the standard shields do not afford absoluteprotection-from the light rays of the welding flame, and in con sequenceof this many welding operators are habitual sufferers from eye and headaches which are brought on not so much from direct light rays from theflame to the eyes, which of course are very injurious and from whichoperators are protected by the standard shields, but from reflectedlight which is quite intense and passes around the back of the shieldespecially if welding is being done in a normally dark place.

My shield is particularly designed to'overcome the foregoingdiffieultiesand consists of a device constructed and arranged all as hereinaftermore particularly described and illustrated by the accompanyingdrawings, in which Fig. l is a rear perspective view of my device.

Fig. 2 is a vertical cross sectional view through the window and facefitting portion of my shield, and

Fig. 3 is a plan view of my device, the outer portion of the shieldbeing broken away.

Like characters of reference indicate corresponding parts in thedifferent views.

My device consists of ,a substantially curved rectangular shield'portion1 which is of a size sufficient to keepthe direct rays of the weldingflame away from the face of the operator.

Centrally ofthe shield I filtering glass window 2'and a face fittingguard member 3 which extends rearwardly of the shield from the window 2.

- Upon reference toFig. 2 the exact construction and relation of mywindow and'faee fitting guard will be clearly seen. Centrally of theshiel d'l, is formed a rectangular; orifice at and upon the outer faceof the shield around such orifice is attached a reetangularlframe 5 by aplurality of rivets 6. The outer face '2 is contained.

' eluded from the eyes.

position a light of the frame 5 is of open form and constitutes abezelin whichthe coloured glass My face fitting guards is constructed ofsoft material such as rubber or pliable leather and is of tubular form.The outer end ofseen upon reference to Figs. 1 and 3, the upper edge 8of the member being curved to fit the curvature of the forehead, and thelower edge 9 being curved to follow the curvature of the cheeksunderneaththe eyes and the bridge of the nose; so that 'when the face ofa the operator is pressed comparatively tightly against the resilientouter edge of the guard anyoutside source of light other than thatreceived through the window 2 will be ex- The inner end 10 of the guardis of the same o uter dimensions as the inner dimensions of the frame 5andsuch end is inserted thereinto. Interiorly of the inner. end of theguard I position a metal sleeve 11 which keeps such inner end rigid andretains it in relation to the frame 5, the sleeve being connected to theguard by means of a plurality of rivets 12. In order that the guard maybe conveniently held to the operators face I furnish a handle 13 whichextends downwardly from the lowenfaee of the frame 5. I

his face so that the edge of suehouter end remains in close allaroundeontact with his rays from his eyes other than the filtered rayspassingthrongh the window 2.

It has been found in practice that my shield as described in theforegoing specification is of great value to the welding operator andthat when consistently and correctly used eliminates all eye trouble dueto ex posure to the direct or reflected rays.

lVhat I claim as my invention is In a device of thecharacter described,a

face guard having an orifice therein, a'window-containing rectangularframe member surround ng the orifice and extend ng for face, thusexcluding any direct or reflected Wardly from the face guard, a singlepliable tubular guard for both eyes extending the length of the framemember and protruding rearwardly therefrom, the rear edge of the guarc lbeing formed to make close contact with the operators face atallpointsof its edge,a i1d a rigid sleeve Contained Within the tubular guard andthe franie and extending rearwardly intermediately of the length of therearwardly extending protruding portion of the pliable tubular guard toform a support therefor whereby the outer eiid-of the guard remainspliable for light excluding contact with the operators face.
